Fluid type explained

The 2018 Ford Escape uses Motorcraft MERCON LV ATF. This is a synthetic blend fluid designed for modern Ford automatic transmissions. It offers excellent protection against wear and tear, and it provides consistent shift quality in a wide range of temperatures. MERCON LV is not compatible with older MERCON V or other fluid types. Using the wrong fluid can lead to shift problems, and it may even cause internal transmission damage.

Service procedure

There are two main ways to service the transmission fluid in your 2018 Ford Escape: a drain and fill, or a full fluid exchange. A drain and fill is the simpler method, and it's the one recommended by Ford for routine maintenance. It involves draining the old fluid from the transmission pan, and then refilling it with fresh fluid. This method typically replaces about half of the total fluid in the transmission.

A full fluid exchange is a more thorough process that replaces nearly all of the old fluid. This is typically done with a machine that connects to the transmission cooler lines. The machine pumps new fluid into the transmission while simultaneously drawing out the old fluid. This is a more expensive service, but it's a good idea if the fluid is very dirty or if you're experiencing shift problems.

Service interval

Ford recommends a transmission fluid and filter change every 150,000 miles for normal duty driving. However, if you use your Escape for towing, or if you do a lot of driving in heavy traffic or mountainous terrain, you should consider servicing the transmission more frequently. A good rule of thumb is to change the fluid and filter every 30,000-60,000 miles for severe duty use.

Common transmission problems

The 6F35 and 6F55 transmissions are generally reliable, but there are a few common problems to be aware of. Some owners have reported harsh or delayed shifting, and in some cases, the transmission may slip or fail to engage a gear. These problems can sometimes be caused by low or dirty fluid, but they can also be a sign of a more serious internal problem. If you're experiencing any of these issues, it's a good idea to have your vehicle inspected by a qualified technician as soon as possible.

Another common issue with these transmissions is a fluid leak from the axle seals. This is a relatively minor problem, but it's important to have it repaired to prevent the transmission from running low on fluid.
